Our Mouse Dynamics is an advanced behavioral detection signal designed to identify sophisticated bot behavior and malicious users in real time.
While automated scripts can spoof IP addresses or device specs, replicating natural human movement on a screen is significantly harder. By tracking cursor behavior and interaction patterns, Fraud Blocker adds a powerful layer of protection against automated click fraud.
What are Mouse Dynamics?
Mouse Dynamics analyzes how a visitor interacts with your website using their mouse or pointing device. By evaluating raw telemetry data—including high-precision coordinates ($x, y$), timestamps, and event triggers—our behavioral engine translates cursor movement into actionable fraud intelligence.
Key factors evaluated by our Mouse Dynamics engine include:
Mouse Speed: How quickly the cursor moves across pixels over time.
Mouse Trajectory & Path: The curve, direction, and path directness of the movement.
Mouse Velocity: Acceleration and deceleration changes throughout the movement arc.
Mouse Clicks: Click frequency, hold duration, and click precision.
How Mouse Dynamics identifies fraud
Human navigation is naturally imperfect and organic. When a real person uses a mouse, they exhibit micro-jitters, variable speeds, curved paths, and natural pauses. Automated scripts and click bots, on the other hand, exhibit unnatural patterns.
Mouse Dynamics screens for abnormal behaviors, such as:
Lack of Micro-Jitters: Perfectly straight lines or perfectly linear speed vector patterns that indicate automated movement.
Extreme Speed & Precision: Instantaneous cursor jumps ("teleportation") across coordinates or programmatic, pixel-perfect accuracy.
Excessive or Rapid Clicking: Unrealistic click frequencies, zero-delay multi-clicks, or non-human click hold times.
Abnormal Navigation Paths: Robotic angular path changes without natural acceleration or deceleration arcs.

How Mouse Dynamics affects your fraud score
Every interaction monitored by the Mouse Dynamics engine is assigned a signal score based on its likelihood of being automated or malicious.
Signal Analysis: Raw cursor coordinates, timestamps, and click events are analyzed as a visitor navigates your page.
Behavioral Blending: The individual sub-scores (speed, trajectory, path, click behavior) are blended into an overall Mouse Dynamics behavioral score.
Fraud Score Contribution: This result is weighted alongside our other core detection signals (such as Device Fingerprinting, IP-Device Ratio, and Data Center detection) to incrementally build the visitor’s total Fraud Score for your domain

Frequently Asked Questions (FAQ)
Does Mouse Dynamics affect website load speed or performance?
No. Data collection uses ultra-lightweight, asynchronous telemetry scripts that record coordinates without impacting page rendering or slowing down user experience. Read more about our pixel compression.
Does Mouse Dynamics track touchscreens and mobile devices?
No. Our current Mouse Dynamics only tracks desktop behavior today with a mobile equivalent coming soon.
How does Mouse Dynamics tell a fast human user apart from a bot?
Our engine evaluates dozens of micro-variables simultaneously, not just speed alone. A fast human user still produces subtle micro-movements, slight overshooting, and natural path curvature that bots do not replicate.
